grpcUI on Ubuntu 24.04

Overview

grpcUI is an interactive web user interface for gRPC servers, the graphical counterpart to command line tools like grpcurl. Point it at a running gRPC service and it discovers that service's methods, either automatically through gRPC server reflection or from the .proto or protoset files you supply, then renders an HTML form for each method. You fill in the request fields in the browser, invoke the method, and grpcUI performs the real gRPC call on the server side and shows you the response message, the status code and the response metadata. It is, in effect, a Postman for gRPC: a way to explore, test and debug gRPC APIs by hand without writing a throwaway client.

It suits developers and QA engineers building or integrating gRPC services who want to poke at endpoints interactively, confirm a method behaves as expected, or demonstrate an API to colleagues, all from a web page rather than a terminal.

Common uses

• Explore and invoke methods on any gRPC service straight from a browser
• Manually test and debug gRPC endpoints without writing a client
• Give a team a shared, form driven console for calling gRPC APIs
